Proton Conductivity Studies in Zirconium Phosphate/MXenes in PEM Fuel Cells
Polytetrafluoroethylene (PTFE) supported proton conductive membranes have become very attractive materials for portable electrochemical applications. In this study, we evaluate two-dimensional titanium carbide (Ti3C2Tx) – MXene, to prepare PTFE supported proton exchange membranes. MXene was incorporated as a dopant within the solid proton conductor-Zirconium phosphate (ZrP). An ionic liquid (IL) and polyethylene glycol (PEG) were used as structure directing agents. The membranes’ proton conductivity was calculated in view of varying two factors, namely: the amount of PEG and the amount of the IL. The membranes’ proton conductivities were evaluated via the use of the electrochemical impedance spectroscopy (EIS) technique. The experimental results showed that the addition of the IL significantly enhanced the proton conductivity for ZrP/MXene/PEG. The proton conductivity values for ZrP/MXene/PEG and PTFE/MXene/PEG/IL membranes were 0.006 S.cm-1 and 0.05 S.cm-1, respectively. Enhanced proton conduction in the latter was attributed to the ability of the IL component to provide additional proton transfer paths. The results reported in this work suggest that the incorporation of MXene in ZrP composite membranes prepared showed great potential be applied in fuel cell applications.
